Topic: The Decompressed C2/686C Block

[TheNattak]

Hello S.P. board. I am trying to locate the correct bytes in the decompressed C2/686C Block documented by Novalia Spirit, and I am having trouble, hoping someone might be able to help a brotha out.

THE MISSION: I'm trying to get the game to loop the title screen over and over without going into the intro (1000 years have passed...) all by itself, so I'm looking here at the document, and I can't seem to locate the correct bytes at the addresses, or anywhere else for that matter. I display the offset to SNES Memory in the hex editor, I think that's right..? I search 'E53BC' and come up with something else completely. Searching for the bytes A9 FF 85 19 is not working for me either really, I thought it was but I was still somewhere else. I also thought since I'm using the FFVI J title screen that everything WOULD be different possibly, but it's the same problem on a clean ROM, as well as simply finding other addresses. This is what I'm trying to locate here:

Title screen part 11, exit
7E/53BC:   A9FF       LDA #$FF
7E/53BE:   8519       STA $19
7E/53C0:   7B         TDC            (Zero A)
7E/53C1:   8D0002     STA $0200      (Acknowledge the title-screen sequence went uninterrupted)
7E/53C4:   60         RTS

7E/53C5:   AA         TAX            (Transfer A to X)
7E/53C6:   7CC953     JMP ($53C9,X)

Remove that line. Weren't you guys supposed to be aces at this event hacking stuff?

That's the first thing I started with actually, but the problem I have there, is that if I edit or erase the
'Set event bit $1E80($1CC) [$1EB9, bit 4]' the intro music gets interrupted by each map that it shows during the intro, and besides that, it does not stop the automated intro from going off. So unless I'm missing something, I'm not sure how that would help. ;*(

Or do you mean remove the CA/5E8E: B2    Call subroutine $CC985B?
That makes it skip the intro all together even on a New Game, so I doubt it. Just want to make sure here.

I know there's something that dictates if there is any .srm data present, because how it will bypass the game loading screen and go right to the intro if a button is pressed, if there is no .srm data present that is. So I can see something potentially bad happening there, so that's why I need to get the intro to loop over and over, until an actual button is pressed, to make it work out.

Basically, I just want to eliminate the automatic intro from going off, while keeping everything else in-tact and working, however possible. Alternatively, if this does not work out, I would be happy with it going right to the 'New Game intro', instead of the automated intro if no button is pressed. There IS an actual reason why I need it to be like this, I've not gone crazy or anything. ^_^

I AM the best there is though at missing the blatantly obvious, so if there is still something I am missing here please let me know! I'm totally fine with looking like an idiot as long as I get it working - and I appreciate your assistance. I'll keep at it here.

Haha, more or less. I much prefer doing flashy flying dragon event battles with a ton of crazy sound effects and character actions though LOL. This kind of event work I tend to get confused and lost rather easily. I've gotten my hands dirty though with setting and clearing event bits and the tedious stuff, but this one's a real biotch so far.

I didn't actually think that part through, and forgot about actually doing a new game. I'm thinking there's a way you can do this with clever branching. I know we "fixed" the bug of the intro "skipping" itself if you waited for it before starting your game, but that's probably not what you're shooting for here. You can get it to work with just events, I'm sure of that.

Alright cool, that's good to know. I'm sure we can think of a way to get it to work then, thanks man. =)

OK, I got it to loop with no issues, was simple and event related as you said. Once I found out what bit exactly was in charge of the title screen if a button is pressed:
[2FF DF:7 Interrupted the progression of the title screen or the opening credits]

It was downhill from there lol.

I moved it over to F1 to make room for the new "IF" command...

CA/5E88: C0    If ($1E80($2FF) [$1EDF, bit 7] is set), branch to $CA5E23 (load game screen)

...and added the new "IF" here: C0    If ($1E80($2FF) [$1EDF, bit 7] is clear), branch to $CA5E33 (the title screen)
in between these two, and she works!

CA/5E8E: B2    Call subroutine $CC985B (intro)

So basically, if no button is pressed, it branches back to the title screen. And everything else is in working order still also lol.
